Chutes or hoppers 39 are carried by the trame 23 aud ar ranged so that the rubbish elevated will be dumped therein. These hoppcrs SS) are urovided with beaded mouths 90 around which are secured the sucks G5. A vertical bar 91 is secured to the bars 2G and Qi ot the iii-anic 23 and has hinged thereto as :it 92 casiugs 93 which inclose the lower part of the traine and hide the sacks from view. Spring catches 93 are carried by the plates 27 and which is fixed to the counter-- .lll

marianna coperatewith keepers 93 on the-casillas 93 to hold the latter in place.

There is provided a curved detlector plate 94 which is adjnstably secured to the extensions 790i the trame 34. A canvas or other iiexible apron 95 is secured to one longitudinal edge of the detiector plate 9a and to the cover plate 83 upon the inner side oi3 said coverplate. 'll'he plate 9i is so located as to prevent material swept up by the brush from being thrown upwardly and back of the brush instead of forwardly and upon the elevator (il.

Brace bars 96 are rigidly `connected as at 9i' to the -trame 3l and are hinged asv 'at 98 to extension members 99 which are secured to the plate There is provided a rack 100 on the motorcycle over the rear wheel thereoi i'or the purpose of supporting a number of the sacks 65.

.in operation the motorcycle is started in the ordinary manner and to sweep a street the brush is lowered 'from position shown in Fig. 2 to a position such as will contact with the street.V This is done by movin the lever 37 forwardly, allowing the vframe 3,4 which supports the brush and also the elevator Gl to assume operative position. lThe clutch pedal 5t) is next pushed' downwardly until it snaps under the spring catch (i0,

vThis causes a rotary motion `to be 'transmitted from the pinion 5 to the pinion 55, the countershatt 58, sprockets 75 and 52 on saidcountershatt, chains 50 and '4shafts flo and 72, sprocket chains 44 andlzielt ril(l,`the sprocket 43, shaft G7 and elevator 64, causing the brush 33 to be rotated in a clockwise direction and the elevator to be vrotated counter-clockwise. Rotation of the elevator causes the rubbish swept-up by the brush to be carried upwardly upon theelevator and dumped into the hopperstl which conduct the rubbish into 'the sacks The cover plate 83 and side curtains carried thereby lill lili

together with thehood il practically incase the brush andvelevator and thus scattering otn dust is prevented.' The 'frame 18 being pivoted as at 17 is adapted to swing up wardly when the machine encounters irregularities; thus'shocks and jars aire not com# inunicated to ,the machine.

v By pullingA `the lever 37 'rearwardly the brush and elevator may be rai-sed and held clear of theground `to the extent desired so that the machine may travel freely.l After the sacks (i5 have been filled they may be removed by moving the spring catches 93 'from the keepers 93 and swinging the casinrgs 93 into open position.
